Cobalt Alloy electrode in the process of
welding, after the core is coated with the coating, if used for submerged arc
automatic welding, electroslag welding, gas shielded welding, gas welding and
other welding methods for filling metal, the melted coating A layer of slag is
formed to compensate for the burning of the alloying elements, and the weld
metal must be protected from the weld by the coating and slowly cooled to reduce
the possibility of generating pores.

Cobalt Chrome Alloy electrode is a molten
electrode for coating electrode arc welding, which is composed of a coating body
and a welding core. The chamfer at the front end of the electrode has a chamfer
of about 45°, which is for the purpose of arc ignition. There is a section of
bare core at the end, which accounts for about 1/16 of the total length of the
electrode, which facilitates the clamping of the welding tongs and facilitates
electrical conduction.

The diameter of the cobalt alloy electrode is actually the diameter of the
core. It is usually 2, 2. 5, 3. 2 or 3, 4, 5 or 6 mm, etc., commonly used is
small 3. 2 small 4, small 5 three, the length "L" is generally between 250^-450
mm.

The mechanical properties of cobalt alloy electrodes catch up to even exceed
the basic metals. Will reduce the interaction of molten metal and air. In the
welding process, it has the following effects: improving the stability of arc
combustion. Reducing agents (such as manganese, silicon, titanium, aluminum,
etc.) need to be added to the electrode coating to directly affect the quality
of the weld.

At the same time, this can improve the stability of the arc and protect the
weld pool. Converting electrical energy into heat, the amount of dust generated
during welding will also decrease. It plays the role of mechanical protection,
metallurgical treatment and improvement of process performance. click
